FIELD OF THE INVENTION

[0001] This invention relates to a pair of shoes, and, particularly, toa pair of mountaineering shoes for climbing up and down a slope, whilekeeping an upright profile.

BACKGROUND OF THE INVENTION

[0002] When a person walks on flat land, the bottoms of his footwear(termed “the soles” in the following), such as a pair of shoes,positioned on the land are kept almost horizontal, and the center ofgravity of his body is generally positioned right above his heels. Thisis the most suitable posture for a human's natural walk (termed “thenatural posture” in the following).

[0003] On the contrary, when a person goes up a slope, the toes of hisshoes as put on the slope are positioned more highly than the heels.Also, it is difficult to keep the natural posture while so walking.Therefore, it is necessary to keep the soles horizontally against theslope by lifting the heel of each shoe high in order to maintain thenatural posture.

[0004] Conventionally, there have been a pair of mountaineering shoesinstalled with supporting equipment in heels of mountaineering shoes(see JP-S42-11251-Y). But, it was necessary for the equipment to bechanged to correspond to each size of these shoes.

[0005] Further, there was a mountaineering fixture having an almostsemicircular-shaped base, which is installed at the arched portion ofthe shoes (see JP-S62-196004-U1). The specification of this devicestates that there are advantageous effects to reduce muscle fatiguearound an arch portion of a foot and leg fatigue because of supportingthe body weight by the arch portions of the feet instead of the heelportions.

[0006] But, it was necessary for the equipment to be changed tocorrespond to each size of these shoes.

[0007] But, these almost semicircular-shaped fixtures for themountaineering shoes have to be fixed to the shoes on a slope, or to beremoved from the shoes and to be carried on flat land. Besides, in orderto fix these fixtures to ordinary mountaineering shoes, it is necessaryto prepare separate fixing tools.

[0008] Although it may be possible to surely reduce the muscle fatiguearound an arch portion of a foot that is caused by supporting the bodyweight by means of the arch portions, there is a problem in that anunstable feeling, caused by shortening the distance between the twosupporting points of a foot for supporting the body weight, mayadversely increase the muscle fatigue of a leg, particularly, the heeland calf under the center of gravity of the body weight.

[0009] Also, shoe soles should be kept almost horizontal, particularlyby lifting the toe of each sole, in descending a slope as well as inascending a slope.

[0010] Furthermore, to walk transversely on a slope, the height of theshoe on the valley side may be adjusted so as to be higher than that ofthe shoe on the mountain side, and the heights of both shoes maypreferably be equal.

[0011] It is an object of the present invention provide a pair of shoeshaving parts for keeping the natural posture despite going up or down aslope.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0069] The embodiments of the present invention are now explained indetail, using mountaineering shoes as examples, by referring to FIGS.1-13, as follows.

[0070] To begin with, mountaineering shoes, the heel portions of whichcan be lifted to ascend a slope, are described (about the first andsecond embodiments).

[0071] Referring to FIGS. 1-4, the first embodiment is illustrated asfollows.

[0072] FIGS. 1-3 show an elevational view of the first embodiment of thepresent invention. In these drawings, mountaineering shoes 1 have ametal base-plate 11, two internal threads 12 a, two externally threadedshafts 12 b screwed into said internal threads 12 a, two U-shapedcramping-members 13, a U-shaped sliding member 14, and a bottom member15.

[0073] The U-shaped base plate 11 is made from a narrow and long metalplate, as shown in FIGS. 1(a) and (b). The base plate 11 is fitted andfastened almost in the middle of the heel portion 4 along the contour ofthe sole and the side of the shoe by means of threaded fasteners, etc.,arranged at appropriate positions. This base plate may be made fromplastic materials or porcelain material, etc.

[0074] The U-shaped base plate 11 comprises arms 11 a and a base member11 b, which is in contact with the heel 4, as shown in FIGS. 1(a) and(b). An externally threaded pin 12 b for fitting a set nut 12 a is fixedalmost in the middle of each arm 11 a, and projected therefrom.

[0075] The externally threaded pins (set bolt) 12 b fixed to the twoarms 11 a of the base plate 11 may be arranged as one shaft which goesthrough the heel 4. Such a shaft 12 a is not only fixed firmly to thebase plate 11, but also to the heel 4. Therefore, the mountaineeringshoe 1 can be used in a stable condition.

[0076] FIGS. 2(a) and (b) show structures of a U-shaped cramping-member13, a U-shaped sliding member 14 and a bottom member 15.

[0077] In FIG. 2(a), two clamping-members 13, each of which is made froma rectangular metal plate, are arranged in contact with both sides ofthe base-plate 11. Each clamping-member 13 has a hole 13 a almost in themiddle of the member to be fitted in the set bolt 12 a. But, theclamping members do not have to always be a rectangular metal plate. Themember may be a round plate. The size of the member is not so important.The clamping-members 13 may not be used in some conditions.

[0078] Though the sliding member 14 is illustrated as a rectangularmetal plate, and shown in FIG. 3(a), the shape of the U-shaped slidingmember is also not limited to such a rectangular metal plate. Thesliding member 14 is longer than the clamping member 13, to slide in awide range. Further, a slit for longitudinally guiding the slidingmember 14 is arranged almost in the middle of the sliding member 14

[0079] Also, the clamping member 13 may have rims (not shown in thedrawings) in both sides of the member 13, extending longitudinally, forkeeping the sliding member 14′ slidable. In this case, as the slidingmember 14′ is held firmly, the mountaineering shoes 1 are used safely.

[0080] A small projection (not shown in the drawings) may be arrangedapart from the hole 13 a in the clamping member 13. Then, another oblonghole or slot (not shown in the drawings) for fitting said smallprojection may be arranged in parallel to the oblong hole or slot 14 ain the sliding member 14 in order to ensure the sliding member'soperation.

[0081] As shown in FIG. 2(b), two sliding members 14′ and the bottommember 15 are connected to each other to form a U-shape. Also, thebottom member may be fixed at a position higher than the lower end ofthe sliding members. These U-shaped members need to be made frommaterials having sufficient strength to support a person's weight inmountaineering.

[0082] A U-shaped member 16 comprises two clamping members 13, twosliding members 14, and one bottom member 15 (see FIG. 3(b)).

[0083]FIG. 3(a) shows the operating range of the U-shaped member of themountaineering shoe 1 of the first embodiment of the present invention.

[0084] As shown in FIG. 3(a), the U-shaped member 16 rotates backwardaround the shaft 12 b about 90 degrees, from almost a vertical positionto almost a horizontal position.

[0085] As shown in FIG. 2(a), the clamping member 13 can rotate, butcannot slide. On the contrary, the sliding member 14 can rotate and alsoslide.

[0086]FIG. 3(b) shows a fragmentary sectional view for illustrating aconnecting part of the U-shaped member 16 and members (11, 13, 14, 15)of the mountaineering shoe 1.

[0087] In said connecting part, the externally threaded shaft or setbolt 12 b fixed to the base member 11 is fitted into the slit 14 a, thehole 13 a, and the set nut 12 a to be screwed on the shaft or bolt 12 b.The sliding member 14 and clamping member 13 are locked to the armportion 11 a of the base member 11 by tightening the set nut 12 ascrewed into the set bolt 12 b.

[0088] Also, the U-shaped member 16 can be rotated backward about 90degrees from a vertical position to a horizontal position by looseningthe set nut 12 a, as shown in FIG. 3(a).

[0089] When the U-shaped member 16 is rotated vertically, and then thesliding members 14 are lowered and locked to the lowest position, theheel of the mountaineering shoe 1 is at the highest position. When theU-shaped member 16 is rotated horizontally, the height of the heel 4 isarranged in the lowest position, which is equal to the heel 4 itself.Therefore, if the U-shaped members 16 of a pair of the mountaineeringshoes 1 is kept horizontal, it is no obstacle for walking on a flatplace using said mountaineering shoes 1.

[0090] To rotate the U-shaped member 16, while it is fixed to themountaineering shoe 1, backward and horizontally so that the bottommember 15 does not collide with the heel 4, the radius of the bottommember 15 can gyrate or the length from the shaft 12 b to the bottommember 15 must be made sufficiently longer than the length from theshaft 12 a to the rear end of the heel 4 by regulating the position ofthe sliding member 15 (see FIG. 3(a)).

[0091] Next, how to regulate the height of the heel is explained asfollows.

[0092] The set nuts 12 a in both sides for fastening the clamping member13 and the U-shaped sliding member 14 to the base member 11 are loosenedto begin with. Then, the U-shaped member 16 is rotated to apredetermined position. The height of the heel portion is regulated to asuitable value. The clamping member 13 and the sliding member arefastened to the base member 11 by tightening the set nuts 12 a.

[0093] For a slope with a big angle of inclination, the U-shaped member16 is rotated vertically by loosening the set nuts 12 a, and the slidingmembers 14 are pushed down and adjusted to a suitable height. TheU-shaped member 16 and the sliding members 14 are fastened to theclamping member 11 by tightening the set nuts 12 a.

[0094] Therefore, the height of the heel portion 4 of the mountaineeringshoes 1 can be adjusted by using the U-shaped member 16 to keep thenatural posture.

[0095] Also, though the set nut and bolt are adopted for fastening theU-shaped member 16 to the clamping member 11 in the above embodiments,any fastening means can be used, if it surely fastens the U-shapedmember 16 to the clamping member 11.

[0096]FIG. 4 shows an alternative of the fixture of the firstembodiment. This embodiment comprises a clamping member 11, a U-shapedmember 13, a ring 17, cyclic through holes 17 a, and a projection 18.

[0097] The central portion of the ring member 17 is fixed to the shaft12 of the base member 11 so that the ring member 17 can be rotatedwithin a predetermined angle range (90 degrees in FIG. 4a). A pluralityof through holes 17 a are arranged at a constant angle on a circle ofthe ring 17. The projection 18 is engaged in one of these through holes17 a.

[0098] The projection 18, which is arranged toward the toe side andapart from the shaft 12, as shown in FIG. 4(a), is projected outwardfrom the base member 11 by a compressive force of a spring.

[0099] According to the above variation of the first embodiment, theprocedure for adjusting the height of the heel portion 4 is explained asfollows. The projection 18 is disengaged from one of the through holes17 a by pushing the projection 18 inside the base member 11 from saidthrough hole 17 a. When the height of the heel portion corresponds tothe angle of inclination of the slope by rotating the U-shaped member 13together with the ring 17, the projection 18, projecting from the insideof the base member 11, is engaged in an appropriate through hole 17 aand then the U-shaped member 13, together with the ring 17, is fixedsurely to the base member 11 to achieve the appropriate height of theheel portion, i.e., corresponding to the angle of inclination of theslope.

[0100] As mentioned above, the variation of the fixture of the firstembodiment adopts the ring 17 and the projection 18 of a spring-typeinstead of the set nut 12 a and bolt 12 b, to fix the U-shaped member 13to the base member 11. Therefore, according to this variation, it ispossible to adjust the height of the heels of mountaineering shoes in ashorter time than with the embodiment adopting the set nut 12 a and bolt12 b, and to improve the convenience of users.

[0101] This variation may comprise a U-shaped sliding member like theU-shaped sliding member 14 shown in FIG. 3, instead of the U-shapedmember 13 shown in FIG. 4(b). Using this type of U-shaped slidingmember, the height of the heel 4 can be adjusted more easily by rotatingand sliding the U-shaped sliding member than by using that of thisvariation.

[0102] Further, FIG. 13 shows another variation of the fixture of thefirst embodiment, as the fifth embodiment, as illustrated below. Theupper end of the base member 11 is bent rearward at a right angle, as anarm plate. The second shaft 39, like the first shaft 12, is arranged inthe arm plate. The clamping member 13 or the U-shaped members 13, 14 ofthe fixture 16 are supported by diagonal-bracing members 40. One end ofeach diagonal bracing member 40 is rotatable about a pivot arranged atan end 41 of the member 40. A plurality of notches 42 are arranged inone side of the member 40. One of the notches 42 is engaged with thesecond shaft 39 to support the U-shaped members 13, 14.

[0103] The fixture mentioned above that comprises such a diagonalbracing member 40 can be adapted to the front part of the mountaineeringshoe 3 as shown in FIGS. 8-10. The width of the diagonal bracing membermay be less than that of the member 40.

[0104] Referring to FIGS. 5-7, the second embodiment is illustrated indetail as follows. FIGS. 5(a) and (b) show the fixture for walking ofthe second embodiment of the present invention. This mountaineering shoe2 comprises two set screws 21, one U-shaped member 22, and two cylinders23.

[0105] The U-shaped member 22 includes two vertical arm members 22 a anda base member 22 b fixed to both bottom ends of said vertical armmembers 22 a. The number of vertical arm members corresponds to that ofthe cylinder members 23, illustrated below, and may be more than two.The cylinder members 23 are arranged apart from each other atappropriate intervals. The vertical arm member 22 a needs to slide inthe cylinder member 23. Therefore, for example, an internal diameter ofthe cylinder member 23 is slightly larger than the external diameter ofthe vertical arm member 22 a. But, the cross-sectional shapes of thesemembers do not always need to be circular or rectangular.

[0106] Two cylinders 23 are fixed almost vertically for the sole surface(i.e. the ground) at constant intervals to the back of the shoe 2 bymore than one set screw (the connecting section is not shown in thedrawing). The cylinders 23 are arranged in parallel so that the paralleland vertical arm members 22 a can slide in the cylinders 23.

[0107] Each of the cylinders 23 is hollow and arranged with a hole 23 aat an appropriate height (preferably less than that of the center of thecylinder 23) for being screwed at right angles against the back of themountaineering shoe by the set screw 21 (refer to FIG. 5(a). The hole 23a is threaded for being screwed by the set screw 21.

[0108] The vertical arm members 22 a of the U-shaped member 22 arelocked at an appropriate position of the cylinders 23 by screwing theset screw into the threaded hole 23 a and tightening the set screw tothe arm member 22 a. The cylinder 23 may be made from any material withthe desired strength, other than metal.

[0109] Further, a plurality of transverse slots or recesses 22 c forengaging the tip of the set screw 21 are preferably arranged at constantintervals on the surfaces of the vertical arm members 22 a in order tosurely lock the U-shaped member 22 to the cylinder 23 by a set screw 21,as shown in FIGS. 5(a) and (b).

[0110] Also, like in the first embodiment, when the U-shaped member 22is inserted most deeply into the cylinder 23, the bottom member 22 b ofthe U-shaped member 22 can be adjusted so as not to contact the ground,so that it is not troublesome for walking on a flat place, while eachinstrument, as mentioned above, is installed.

[0111] The second embodiment differs from the first embodiment in thatthe arm members 22 a of the U-shaped member 22 slide up and down in thecylinders 23 and are locked to said cylinders 23 by screwing the setscrew 21 into the threaded hole 23 a and tightening the set screw 21 tothe slot or recess 22 a.

[0112] Next, the procedure for adjusting the height of the heel 4 of theshoe 2 is illustrated as follows. Referring to FIG. 5, two set screws21, fastening the U-shaped member 22 to the cylinder 23, are loosened.The two vertical arm members 22 a of the U-shaped member 22 are slid toadjust the height of the heel 4. The U-shaped member 22 is locked to thecylinder 23 at an appropriate height of the heel 4 by tightening the setscrews 21.

[0113] In addition, according to the second embodiment, the holes 23 ashould be positioned only within the range for arranging the slots orrecesses 22 c, in order to firmly maintain the height of the heel 4 byengaging the set screw 21 in one of the slots or recesses 22 c.

[0114] Consequently, a man can maintain his natural posture by adjustingthe height of the heel 4 of the mountaineering shoes 2, using theU-shaped member 22, etc., while he walks while wearing a pair of themountaineering shoes 2 installed with the fixture for a slope, accordingto this embodiment.

[0115] FIGS. 6(a) and (b) show another variation of the fixture of themountaineering shoe 2 of the second embodiment. The mountaineering shoe2 comprises one U-shaped member 22, two cylinders 22 a, one bar 24, andtwo projections of a spring-type 25. Though the fixture of thisembodiment is illustrated, a redundant description is omitted. Theconfiguration of the cylinder 23 may be either a circular- orangular-type. Also, the type of the cylinder 23 is not limited to theabove-mentioned type, or the previous embodiments.

[0116] A small hole 23 a is arranged in each of the cylinders 23. Aplurality of recesses 22 d are arranged at constant intervals in each ofthe cylinders 23. The recesses 22 d are engaged via the small hole 23 ain a spring projection, which is backed by a spring, as illustratedbelow. Therefore, the height of the U-shaped member 22 is adjusted andthe member 22 is locked. That is to say, the height of the heel 4 can bekept at a desired value. Also, what can be engaged in the springprojection 25 may be the slots 22 c (as mentioned above).

[0117] According to this embodiment, as the spring projection 25 is nota set screw, this small hole 23 a does not need to be threaded.Therefore, it is advantageous in that the cylinder 23 can bemanufactured more easily than other variations of the second embodiment.

[0118] The spring projections 25, engaged in the recesses 22 d, arearranged in correspondence with the number of cylinders 23. All of themare fitted in one bar 24. Therefore, the bar 24 is pressed by all of thespring projections 25.

[0119] Next, the procedure for adjusting the height of the heel 4 of theshoe 2 is illustrated as follows. By drawing out the bar 24 toward theoutside of the cylinder 23, the connection between the recess 22 d andthe spring projection 25 is released and then the U-shaped member 22 isslid up or down to adjust the height of the heel 4 in accordance withthe angle of the slope. By stopping the drawing of the bar 25 tomaintain the height, the spring projection 25 is engaged in theappropriate recess 22 d. The U-shaped member 22 is simultaneously lockedthere. Accordingly, the height of the heel 4 is set at the appropriateposition.

[0120] As mentioned above, according to the variation of the fixture ofthe second embodiment, the spring projection 25 is used instead of theset screw 21 to fix the U-shaped member 22 in the cylinder 23 at adesired position. Therefore, as the spring projection 25 can fix theU-shaped member 22 to the cylinder 23 more easily than can the set screw21 screwed into the slot 22 c of the U-shaped member 22, this variationcan improve the convenience of the mountaineering shoes 2 with thefixture for walking on a slope to quickly adjust the height of the heel4.

[0121] FIGS. 7(a) and (b) show another variation of the U-shaped member22 of the mountaineering shoe 2 of the second embodiment of the presentinvention. The mountaineering shoe 2 comprises one set screw 21, onecylinder 23, and one sliding plate 26. This mountaineering shoe 2, shownin FIGS. 7(a) and (b), differs from other mountaineering shoe shownFIGS. 5 or 6 in using one cylinder 23 and one sliding plate 26, withoutthe bottom member 22 b.

[0122] The cylinder 23 is rectangular. In it the sliding plate 26 isarranged to be slidable. Like the cylinders 23 shown in FIGS. 5 and 6,the cylinder 23 shown in FIG. 6 is arranged on the back of themountaineering shoe 2, and has a threaded hole 23 a, in which a setscrew 21 is screwed to lock the sliding plate 26 to the cylinder 23, atan appropriate height (preferably, below the center of the cylinder 23).Also, this cylinder may be made from any material which has anappropriate strength, except metal.

[0123] The sliding plate 26 is a rectangular pillar and has recesses orslots 26 a, for engaging the set screw 21, at constant intervals, asshown in FIGS. 7(a) and (b). This sliding plate may also be made fromany material which has an appropriate strength. But, as the metalfixture makes the back of the shoe heavy and creates problems inwalking, the fixture is preferably made from a lightweight andreinforced plastic material.

[0124] Further, the fixture of this embodiment does not need a bottommember 22 b, which uses one siding plate 26, while the fixtures shown inFIGS. 5 and 6 use more than one vertical arm member 22 a. Therefore, itis advantageous in that this variation can reduce the number ofcomponents and simplify the manufacture of the fixture formountaineering, compared with other variations.

[0125] Also, though FIGS. 7(a) and (b) show one set screw for fasteningthe sliding plate 26, a plurality of set screws and small holes may beinstalled at constant intervals, vertically or horizontally. Instead ofthe set screws, the bar having the spring projections as shown in FIG. 6may be adopted. Of course, it goes without saying that a plurality ofset screws more firmly fasten the sliding plate 26 to the cylinder 23than does one set screw.

[0126] Next, as the procedure for adjusting the height of the heel 4 ofthis variation is similar to the procedures of the variations shown inFIGS. 5 and 6, its description is abbreviated here to avoid repeatingit.

[0127] Subsequently, a mountaineering shoe with a fixture to adjust theheight of the shoe's toe for descending a slope is described as follows.

[0128] FIGS. 8-10 show the structures of the mountaineering shoes 3 withfixtures for walking on a slope according to the third embodiment of thepresent invention. The mountaineering shoes 3 comprise a base member 31,two female set screws or threaded holes 32 a, two clamping members 33, aU-shaped sliding member 34, and a bottom member 35.

[0129] As the structures of the two clamping members 33, the U-shapedsliding member 34, and the bottom member 35 are similar to those of thefirst embodiment, the structures are illustrated using FIG. 2 of thefirst embodiment. In this case, according to this embodiment, thereference numerals are replaced as follows: the clamping member 13 with33, the threaded hole 13 a with 33 a, the U-shaped sliding member 14with 34, and the hole for sliding 14 a with 34 a.

[0130] The structure of the base member 31 is similar to that of thebase member 11. Referring to FIGS. 8(a) and (b), the base member 31 isU-shaped and fitted to the toe part 5 of the shoe 3 between the middleand the tip of the toe part 5 of the shoe 3 along the sole and the sideof the shoe 3, and fixed to the sole in arbitrary locuses by set screws.

[0131] Two externally threaded shafts or two set screws 32 b may beformed as one threaded shaft like in the first embodiment. As thisthreaded shaft goes through the toe part 5, the shaft is firmly fixed tothe base member and the toe part of the shoe 3. Therefore, themountaineering shoes are used safely.

[0132] The structure of the clamping member 33 is similar to that of theclamping member 13 of the first embodiment (see FIG. 2(a)). A threadedhole 33 a is to be arranged in the middle of the clamping member 33.

[0133] The structure of the sliding member 34 is similar to that of thesliding member 14. A lengthwise slot 34 a is to be arranged in themiddle of the sliding member 34 (see FIGS. 2(a) and (b).

[0134] Like in the first embodiment, the clamping member 33 may haveparallel rims, which hold the sliding member 34, at both sides of themember 33 (not shown in the drawings). In this case, as the slidingmember 34 is firmly held by the parallel rims, the mountaineering shoes3 are used safely.

[0135] The bottom member 35 is fixed to each end of the sliding members34 substantially at right angles.

[0136]FIG. 9 shows the operating range of the fixture 36, which isinstalled in the mountaineering shoe 3, comprising the clamping member33, the U-shaped sliding member 34, and the bottom member 35.

[0137] The fixture 36 is formed into a shape like a U. The fixture 36can be rotated over 90 degrees around the threaded shaft 32 b toward thetip of the shoe 3 from a position almost perpendicular to the surface ofthe sole or the ground to another position at the level of or above thetoe by loosening the set nuts 32 b for fastening the clamping member 33and the sliding member 34 to the base member 31.

[0138] When the U-shaped fixture 36 is positioned horizontally or abovethe toe, the height of the toe of the shoe 3 becomes at its lowestposition. Then, the U-shaped fixture 36 is fixed to the base member 31by tightening or screwing the set nuts 32 a into the threaded shaft 32 band kept in the position equal to or above the level of the tip of thesole. Therefore, the mountaineering shoes are used safely for walking ona flat place.

[0139] According to this embodiment, and like in the first embodiment,it is possible to adjust the height of the toe 5 within a wide range bythe U-shaped fixture 36 rotating to a desired angle or to a verticalposition and, additionally, by the sliding member 34 sliding to itslowest point at the vertical position, particularly for a steep slope.The U-shaped fixture 36 is fixed at the desired position to the basemember 31 by screwing the set nuts 32 a into the threaded shaft 32 b.Consequently, the height of the toe part 5 can be adjusted in accordancewith the angle of a slope.

[0140]FIG. 10 shows another variation of the fixture 36 of themountaineering shoe 3 of the third embodiment of the present invention.The mountaineering shoe 3 comprises a base member 31 (not shown in thedrawing), two shafts 32, two sliding members 34, a bottom member 35, tworings 37, a plurality of through holes (arranged on a circle of the ring37) 37 a and a spring projection 38. This variation differs from theembodiment shown in FIG. 9, in its structure for installing the clampingmember 33 and the sliding member 34 in the base member 31 (not shown inthe drawing).

[0141] In addition, as the structure and function of each of the membersare similar to those of the variation of the first embodiment, theirdescriptions are omitted. Therefore, the effects of this embodiment alsoare similar to those of said variation, except for the differencebetween descending and ascending a slope.

[0142] As mentioned above, according to the first or third embodiment,the mountaineering shoes 1-3 have fixtures for adjusting the height ofthe heel or the toe in accordance with the angle of a slope. One of thestructures comprises the clamping member 13 or 33, the sliding member 14or 34, and the bottom member 15 or 35. Other structures comprise theU-shaped sliding-member 22 or the sliding plate 22 and the cyinders orthe cylinder 23.

[0143] Consequently, as it is unnecessary to fix or remove thesefixtures according to whether one is ascending or descending a slope, orwalking in a flat place, the present invention improves the convenienceof the shoes in that a man can climb a mountain and walk in a flatplace, even in daily life, while the fixture is installed in the shoes.

[0144] According to the present invention, when the man ascends ordescends a slope wearing the shoes, the body weight is supported in twopoints that are separated to some extent. Therefore, the stabilityduring a walk is improved compared with the prior art.

[0145] Further, the shoe may have two fixtures installed, one in theheel and one in the toe, according to the first, second, or thirdembodiment. In this case, the present invention includes the effectsgiven by both the fixtures for walking on a slope and in a flat place ofthese embodiments.

[0146] In reference to FIGS. 11 and 12, the fourth embodiment isdescribed in detail as follows. FIG. 11 shows a structure of amountaineering shoe 10 with a fixture for walking on a slope of thefourth embodiment of the present invention. The mountaineering shoe 10comprises two sets of two set screws 101, one U-shaped member 102, twocylinders 103, and one base member 104, arranged in both sides of themountaineering shoe 10. According to this embodiment, the structures ofalmost all the members arranged in both sides are similar to those ofthe members of the fixture installed in the back of the shoe 2 of thesecond embodiment.

[0147] The structure of the base member 104 is U-shaped and similar tothat of the base member installed in the heel 4 or the toe 5, accordingto the first or third embodiment. The base member 104 is fitted alongthe arched portion and both sides of the shoe 10 and fixed there by setscrews arranged in arbitrary locuses of the member 104.

[0148] The U-shaped sliding member 102 comprises two vertical slidingmembers 102 a arranged at intervals that are equal to those of thecylinders 103 and one bottom member 102 b fixed to each lower end of thesliding members 102 a. Like the second embodiment, the number ofvertical sliding members may be more than two, and thus equal to that ofthe cylinders 103 arranged at intervals in accordance with the number.The sectional configuration of the vertical sliding member may becircular, angular, etc.

[0149] The cylinder 103 is firmly fixed to the base member 104 by setscrews at arbitrary locuses (not shown in the drawings). The cylinders103 are hollow and parallel to each other so that the vertical slidingmember 102 a can slide in the cylinder 103.

[0150] A small hole is arranged at an appropriate height of the cylinder103 and threaded to be screwed by a set screw 101. The cylinder 103 maybe made from any material with an appropriate strength, except metal.

[0151] Further, a plurality of transverse slots or recesses 102 c forengaging the tip of the set screw 101 are preferably arranged atconstant intervals in the surfaces of the vertical arm members 102 a inorder to surely lock the U-shaped member 102 to the cylinder 103 by aset screw 21, as shown in FIG. 11.

[0152] Next, the procedure for adjusting the height of the side of theshoe 10 is illustrated as follows. The mountaineering shoes 10 of thisembodiment are used for walking in a transverse (horizontal) directionon a slope.

[0153] In reference to FIG. 5, two set screws 101 for fastening theU-shaped member 22 to the cylinder 23 are loosened. Two vertical armmembers 102 a of the U-shaped member 102 are slid to adjust the heightof the side of the shoe 10. The U-shaped member 102 is locked to thecylinder 103 at an appropriate height of the side by tightening the setscrews 101 to press the tip of the set screws 101 into the transverseslots or recesses 102 c

[0154] While the height of the U-shaped member 102 on the side facing avalley is fixed at a desired height, the height of the U-shaped member102 facing a side of a mountain is equal to that of the sole by theU-shaped arm member 102 a on the mountain side being inserted mostdeeply (most highly) into the cylinder 103.

[0155] As mentioned above, a man wearing a pair of the mountaineeringshoes 10 with the fixtures of this embodiment can keep almost hisnatural posture in walking transversally on a slope by using theU-shaped member 102, etc., and adjusting the height of the side of theshoe facing a valley.

[0156] An example of the procedure for adjusting the height of one ofthe shoes is illustrated above. Next, other examples of the procedurefor adjusting the heights of both shoes are illustrated as follows. Asthe shoe facing a mountain side is higher than the shoe facing a valleyside in walking transversely on a slope, the shoe on the valley sideneeds to be arranged more highly than the shoe on the mountain side tobetter maintain the natural posture. Assuming, for convenience of adescription, that the man walks transversely and horizontally on a slopeof a mountain while viewing the valley in the right direction (the rightfoot is on the valley's side), this embodiment is described in detail asfollows. After the height of the left shoe is adjusted according to theprocedure mentioned above, the left U-shaped member of the right shoe isdrawn out longer than the right U-shaped member of the left shoe and,furthermore, the right U-shaped member of the right shoe also is drawnout longer than said left U-shaped member of the right shoe, inaccordance with the angle of the slope. According to such procedure,wherein the heights of both shoes differ based on an angle of a slope,the man wearing a pair of shoes with the fixtures of this embodiment cansufficiently maintain his natural posture while walking transversely onthe slope.

[0157] In FIG. 11, instead of two set screws 101 of the mountaineeringshoe 10, a bar 24 with two spring projections 25, each of which isbacked by a spring (shown in FIG. 6), may be used in the mountaineeringshoe 10. As the structure and function of each of the members werealready illustrated in the second embodiment, their illustration anddescription are omitted here.

[0158]FIG. 12 shows another variation of the mountaineering shoe 10 withthe fixture for walking on a slope of the fourth embodiment. In thisdrawing, the mountaineering shoe 10 comprises one set screw 101, onecylinder 103, and one sliding plate 105 in both sides of the shoe 10.The mountaineering shoe 10 with the fixture for walking on a slope,shown in FIG. 12, differs from the mountaineering shoe 10 shown in FIG.12 in using one cylinder 103 and one sliding plate 105, instead of twovertical arm members 102 a and the bottom member 102 b.

[0159] The cross-sectional shape of the cylinder 103 is hollow andrectangular. The sliding plate 105 can slide in the cylinder 103. Likethe mountaineering shoe 10 shown in FIG. 11, the cylinder 103 has athreaded hole 103 a (not shown in FIG. 12), in which a set screw 101 isscrewed to lock the sliding plate 105 to the cylinder 103, at anappropriate height (preferably, below the center of the cylinder 23).Also, this cylinder may be made from any material which has anappropriate strength, except metal.

[0160] The sliding plate 105 is a rectangular pillar and has recesses orslots 105 a, for engaging the set screw 101, at constant intervals, asshown in FIG. 12. This sliding plate 105 also may be made from anymaterial which has an appropriate strength. But, as the metal fixturemakes both sides of the shoe 10 heavy and may bring problems in walking,the fixture is preferably made from lightweight and reinforced plasticmaterial.

[0161] Further, the fixture of this embodiment does not need a bottommember 102 b, because it uses one siding plate 105. Therefore, it isadvantageous in that this variation can reduce the number of componentsand simplify the manufacture of the fixture for mountaineering, comparedwith the variation shown in FIG. 11.

[0162] Also, though as in FIG. 12 one set screw is used for fasteningthe sliding plate 105, a plurality of set screws and small holes may beinstalled at constant intervals vertically or horizontally. For example,instead of the set screws, the bar having the spring projections asshown in FIG. 6 may be adopted. Of course, it goes without saying that aplurality of set screws fasten more firmly than one set screw thesliding plate 105 to the cylinder 103.

[0163] Next, as the procedure for adjusting the height on the valleyside of the mountaineering shoe 10 of this variation is similar to thosevariations shown in FIG. 11, its description is abbreviated here toavoid repeating it.

[0164] As mentioned above, according to the fourth embodiment, themountaineering shoe 10 has the U-shaped members 102 or the slidingmember 105 and the cylinders 103 to adjust the heights of both sides inits arched portion in accordance with the angle of a slope.

[0165] Consequently, a man wearing the mountaineering shoes 10 of thepresent invention can maintain his natural posture more easily inwalking transversely on a slope while climbing a mountain and can walkmore safely than when wearing conventional mountaineering shoes.

[0166] Furthermore, a pair of the mountaineering shoes in which thefixtures of these first four embodiments are selectively installed maybe used. In such cases, the technical contributions are also combinedselectively.
